[ Upstream commit 2ad84af4cff9121827d3dd35e293478bdb0b58bb ]
Under `CONFIG_DRM_PANIC_SCREEN_QR_CODE=y`, zlib is used:
ld.lld: error: undefined symbol: zlib_deflate_workspacesize >>> referenced by drm_panic.c >>> drivers/gpu/drm/drm_panic.o:(drm_panic_qr_init) in archive vmlinux.a
Thus select `CONFIG_ZLIB_DEFLATE`.
